htly present invention relates to hydrocarbon burners adapted for general use in furnaces, boilers, stoves and the like, and has for its object t simplify the same and to improve the operation thereot.

Generally stated, the invention consists of the novel construction and combinations oi? parts hereinafter described and defined in the claims.

Tl e burner designed as illustrated in the accompanying drawings, has been especially designed for use in heaters, boilers, or :hirnaccs of domestic heating plants, but may be mace in various different sizes and applied generally for the burning of heavy hydrocarbon liquids. A. crude oil product,

known as distillate and which is of considerably lower grade than kerosene, is advisably used, but lighter or heavier hydrocarbon oils may be'used.

As preferably designed, the burner is a duplex or twin burner having two generatnozzles. I

In the accompanying drawings, which illustrate the invention in its preterred commercial form, like characters indicate like parts throughout the several views.

Said cones 10. tor another important reason, are made hollow and tapered and, at their apexes or uiiipermost portions, they are tapped by small tuel supply pipes 152 that have contact with the cones only at their upper ends where they connect to said cones.

The :tuel supply pipes-12 are extended downward and thence outward through the fuel door opening 6 and are connected to a common fuel supply pipe 13 that leads trom a suitable source of fluid fuel supply. The branch pipes 12 are shown as provided with independently operative globe valves 14 and with normally open cut-off valves 15, the latter of which are provided. with projectin arms 16 to which weight-acting buckets 17 are attached.

Below their upper portions but above their bottoms, the basins 9 are tapped by small. overflow pipes 18 that lead. down ard and outward through. the door opening 6 and terminate in position to be dischaige ed into the respective buclrets 17. For the purposes of this case. it is only necessary to state that if the flame "from the burner should '0 out and the oil continue to flow thereto, the oil overflowing through a pipe 18 would run into a bucket 17, increasing '.5ht thereof to an extent that would close'the .co-operating cut-oft valve 15.

The base 7 is intended to rest upon the grates 5 and'the grates should be closed, surrounding the base by ashes or any other suitable means so that all of the air passing into the five box of the heater will have to pass upward througha central port 8.

The generating cones or nozzles 10 are concentrically located within the clownturned air tubes 19 ot a bifurcated air dome 20 that is formed between said air tubes with a large depending air intake stack 21.

cones are space ,ioin the pipes 12,

will not be heated any co siderable ':'ten and, hence, will not be carbonized ."thl. said pipe-s ll hen the burner is in action, the cone and especially the depending air tubes 19, and also the generating cones l0 basins 9. will be heated to a high degree of 1- erature, sometimes becoming nearly or quite red hot. Hence, when the oil overflows at the upper ends oi the generatinp; cones, will trickle or run down the same and, because of the increasing diameter of the cones, will be spread thinner and thinner so that, under the action oi LQllSG heat, will be almost. instantaneously vaporized and taken up by and thoroughly commingled with the air, thereby quickly form; ing with the the proper mixture for supporting complete combustion, resulting in the hottest kind of a flame and the format-ion oi little or no carbon. T he steps or ledges on the exteriors oi the cones further retards the speed of lownward travel or tlow of? the oil and hence. gives the air a better chance to absorb the same, so that when the burner is in proper action no oil will reach the basins 9. The mixture will ignite and the flames will start within the depending outward and upward by the then hot basins,

so that there will be produced substantially annular upwardly flaring flames of great intensity.

When heavy oils or hydrocarbons are used, it is advisable to start the burner into action by using a smallpriming oi gasoline, which may be poured into the basins 9 and ignited.

If, for any reason, the flame or one of the burners should go out, the oil will contubes 19 and will be deflected will be such that it will move its lever 16 down and close the co-operatlng cut-oil 15, thereby stopping the further flow to that side of the burner.

means 01' the valves ll, the flow of ides of the burner may be inde- *egulated and, or course, the main ly pipe 13 may be provided with a 'e for si. taneously cutting 0d the supply to both sides of the burner. In actual practice. this burner has been found'highly crhcient for the purposes had in view. It ail ords very complete combustion and can be economically operated ll-loreover, the burner is of very simple construction, hav- 1' no parts that can easily get out of order and, moreover, may be made at comparatively small cost, since the burner proper involves only two castings, to wit: the base and the dome members.

l Jhat I claim is:

l. A burner comprising a base adapted to rest upon grate and having a large angular C81 trallv located opening and, on oppo- 'e Sl(.lGS of said opening, annular basins and cones rising from said basins, in comlsliation with a dome structure having a large ce trally located angular intake stack detachably seated in said angular air passage between said basins and to be held against rotation, said dome having outwardly and downwardly extended air tubes that concentrically surround said cones and terminate above said basins.

2. The structure defined in claim 1 in further combination with fuel-intake tubes lead ing upward through said cones to the upper ends thereof, and overflow tubes lead ing from said basins.

3. A device of the character described comprising a base adapted to rest upon a and having an angular opening therein, a burner laterally offset with respect to said opeing ad provided with an annular basin and a co-operating cone rising from CLAREYOE BERKINS.
